Greatest Common Factor
We found the factors 57,85,330 . The biggest common factor number is the GCF number.
So the greatest common factor 57,85,330 is 1.
Lets's calculate LCM of 77,90,823
Given numbers has no common factors except 1. So, there LCM is their product i.e 5703390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5703390
Therefore, the GCF of Fractions 57/77,85/90,330/823 is 1/5703390
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 77,90,823 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,90,823) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(77,90,823) x common factors =1 x 1 = 1
LCM(77,90,823) = ( 77 × 90 × 823 ) / 1
LCM(77,90,823) = 5703390 / 1
LCM(77,90,823) = 5703390
